Nowadays, biodiesel is an alternative fuel to replace the existing petroleum-based diesel. The advantages of biodiesel are good combustion efficiency, high-lubricity, biodegradability and low toxicity. Biodiesel can be an alternate fuel to be used for running diesel engines. This paper is to...

Potassium impregnated mixed oxides of lanthanum and magnesium in 1:1 to 1:5 atomic ratios were prepared by co-precipitation at a constant pH. These were characterized by FEG–SEM–EDX, TEM, Powder XRD, Hammett indicators and acid/base titration and, were evaluated as heterogeneous catalysts...

The use of MgO impregnated with KOH as heterogeneous catalysts for the transesterification of mutton fat with methanol has been evaluated. The mutton fat (fat) with methanol (1:22 M ratio) at 65 °C showed  98% conversion to biodiesel with 4 wt% of MgO–KOH-2011MgO–KOH-X (X = wt% of...

The transesterification of palm oil to methyl esters (biodiesel) was studied using KOH loaded on Al2O3 and NaY zeolite supports as heterogeneous catalysts. Reaction parameters such as reaction time, wt% KOH loading, molar ratio of oil to methanol, and amount of catalyst were optimized for the...
